How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to protect a pair of kids' JBL JR 300BT/JR 300 on-ear headphones with a crush-resistant, water-resistant shell, choose Aenllosi Hard Carrying Case; if you need an actual pair of lightweight, foldable retro on-ear headphones you can listen with, choose GANPUB 2.
• Aenllosi Hard Carrying Case — biggest strength: a hard EVA shell that is crush resistant, anti-shock and water resistant, so it shrugs off bumps, scratches and splashes.
• Aenllosi Hard Carrying Case — biggest trade-off: it is a case only. No headphones, no cable, no accessories are included, so it is useless on its own.
• GANPUB 2 — biggest strength: two complete wired on-ear headphone pairs in one pack, with a retro orange-and-black look, cushioned ear cups and a foldable build.
• GANPUB 2 — biggest trade-off: wired-only, no noise control, and a sensitivity of 85 dB means they are not built for loud, isolating listening.
• Who Aenllosi is for: a parent or owner who already has JR 300BT/JR 300 kids' headphones and wants them to survive a backpack.
• Who GANPUB 2 is for: someone who wants an inexpensive-looking pair (or two) of retro on-ear headphones for casual wired listening and sharing.
This is a single-purpose product, and that is its whole appeal. The Aenllosi case is a molded EVA shell — Ethylene Vinyl Acetate, the same dense foam-like material used in a lot of protective gear — built specifically as a replacement case for the JBL JR 300BT, JR 300 and other kids' on-ear wireless headphones. EVA is the reason it can claim crush resistance, anti-shock behavior and water resistance all at once. It is not a soft pouch that keeps dust off; it is a rigid box meant to take a hit so the headphones inside don't.
The dimensions tell you what it actually holds. External size runs about 7.3 x 5.5 x 2.4 inches, internal size about 6 x 2.5 inches, and the whole thing weighs roughly 150 g. That is a small, light, kid-sized footprint — easy to drop into a school bag or a carry-on without eating much space. The blue solid-color exterior and sport-style theme keep it plain and durable rather than flashy, which fits the audience: kids and the adults who pack for them.
Inside, there is a mesh pocket for accessories, so a charging cable or a small adapter has somewhere to live instead of rattling loose against the ear cups. That is a genuinely thoughtful detail for a case at this level.
Who should buy it: anyone who already owns JR 300BT/JR 300 kids' headphones and is tired of them getting squashed, scratched or splashed in a bag. Who should skip it: anyone who does not own those specific headphones, and anyone expecting headphones to arrive in the box. The listing is explicit — case only, device and accessories are not included. If you want headphones, this is the wrong product entirely.
The GANPUB 2 is the opposite kind of purchase: it is the headphones themselves, and you get two pairs. The pack contains two wired on-ear headphones in an orange-and-black retro colorway, plus a user manual. Ear placement is on-ear with round ear pieces, and the enclosure mixes metal and plastic — which is a reasonable combination for a lightweight, portable frame. At roughly 60 g for the item weight, these are genuinely light on the head.
The design brief here is clearly nostalgia. Adjustable headband, cushioned ear cups, foldable structure, classic cassette-player-era styling. The adjustable band and soft cups are what make extended listening sessions tolerable, and the foldable build is what makes them easy to toss in a bag or a jacket pocket. Wired connectivity over a 3.5 mm jack is the whole point: it works with cassette players, older stereos, laptops and anything else with a standard headphone port, with no pairing, no charging and no battery to die mid-trip.
On the audio side, the specs are modest and honest. Dynamic drivers with a 20 Hz to 20,000 Hz frequency range cover the full audible band on paper, which is what you want for general music playback. Sensitivity is listed at 85 dB, and there is no noise control at all — no active noise cancellation, no isolation claims. That means these are for quiet-to-normal environments where you are listening deliberately, not for drowning out a plane cabin.
Two pairs in one pack is the feature that changes how you use them. One for you, one for a partner or a kid, or one as a backup when the first pair gets lost. Who should buy them: retro-style fans, cassette and vintage-gear users, anyone who wants a cheap-feeling-risk-free wired pair for casual listening, and households that want two sets at once. Who should skip them: anyone who needs wireless freedom, noise cancellation, or serious isolation. There is also no warranty listed, which is worth knowing before you commit.
• Best for protecting existing kids' headphones → Aenllosi Hard Carrying Case. The EVA shell, crush resistance and water resistance are the entire point.
• Best for actually listening to music → GANPUB 2. The Aenllosi product makes no sound at all; it is a case only.
• Best for travel and packing → Aenllosi for the gear, GANPUB 2 for the ears. The case is compact and rigid at about 7.3 x 5.5 x 2.4 inches; the headphones fold and weigh about 60 g.
• Best for sharing → GANPUB 2. Two complete pairs ship in the pack, so two people can listen at once.
• Best for cable-free convenience → neither. GANPUB 2 is wired-only over 3.5 mm and Aenllosi is not a device. If you need Bluetooth headphones, look elsewhere.
• Best for noisy environments → neither, honestly. GANPUB 2 has no noise control and 85 dB sensitivity, so it is not a noise-cancelling pick.
• Best for kids → Aenllosi. It is explicitly designed around JBL JR 300BT/JR 300 kids' on-ear headphones and listed for a kid age range.
• Best for retro style → GANPUB 2. Orange-and-black with an adjustable headband and cushioned cups; the Aenllosi case is plain blue.
In my opinion, these two products are not really competitors — they solve different problems, and the "versus" only makes sense if you know which problem is yours. If you already own JBL JR 300BT/JR 300 kids' headphones and want them to survive real life, I would buy the Aenllosi Hard Carrying Case: the hard EVA shell, mesh pocket and kid-sized footprint do exactly one job well. If you need headphones to listen with, the case is irrelevant, and I would buy the GANPUB 2 for its two-pair pack, foldable retro build and simple wired reliability. Buy the one that matches what is missing from your bag — protection or sound.
what are the best open ear headphones
I can't rank open-ear models here, and neither product on this page is open-ear. The Aenllosi item is a hard case for JBL JR 300BT/JR 300 kids' on-ear headphones, and the GANPUB 2 is a wired on-ear headphone with round ear pieces and cushioned cups. If open-ear is your requirement, neither of these fits it.
are on ear headphones good
On-ear headphones like the GANPUB 2 sit against the ear rather than around it, which keeps them light — around 60 g here — and easy to fold and carry. The trade-off is that on-ear designs with no noise control, like this one, let outside sound in. They are good for casual wired listening, not for blocking out noise.
are open ear headphones good
That depends on your priorities, and again, neither product here is open-ear. The GANPUB 2 is a closed on-ear design with metal and plastic enclosures and no noise control, so it does not isolate. If you want the open-ear experience specifically, this page won't get you there.
what are the best in-ear headphones
Not covered here. The GANPUB 2 is an on-ear headphone, not in-ear, and the Aenllosi product is a carrying case with an internal size of about 6 x 2.5 inches built for over-ear kids' headphones. For in-ear options you would need to look at a different category entirely.
